# Attachment

An asset provided to the model.

## Declaration

```swift
struct Attachment<Content> where Content : AttachmentContent
```

## Mentioned in

Analyzing images with multimodal prompting

## Overview

Overview Use Attachment to include media such as images alongside text in your prompts and instructions. let response = try await session.respond {     "Describe this image:"     Attachment(image) } Use the label(_:) method to assign a label to an attachment. Labels help the model identify specific attachments when making tool calls. Prompt {     "Compare these two images:"     Attachment(firstImage)         .label("image-0")     Attachment(secondImage)         .label("image-1") }
